Abstract: 【Abstract】 Objective〓To evaluate the risk factors for conversion of laparoscopic to open surgery for colorectal cancer. Methods〓A retrospective analysis of our hospital from January 2002 to January 2012, a total of 813 cases of laparoscopic colorectal resection were retrospectively analyzed, including 68 patients converted to open surgery. The clinical baseline data, perioperative data, short-term clinical efficacy were compared between laparoscopic and conversion groups. Results〓The rate of conversion to open surgery was 8.3%(68 patients). Stage IV, T4 stage, tumor length >5 cm, surgical procedures, abdominal surgery history were significantly associated with the risk of conversion to open surgery. In terms of surgery-related data,although laparoscopic group had slightly longer operation time, conversion group had more blood loss during surgery(262.4 ml vs 104.3 ml, P <0.001) and blood transfusion (126.8 ml vs 17.8 ml, P<0.001). In terms of short-term clinical efficacy, the time to soft diet (3.82 vs 4.63 day, P<0.001), time to flatus (2.95 vs 3.41 day,P<0.001), time to ambulation (2.37 vs 3.14 day, P<0.001), and length of hospital stay (18.9 vs 22.4 day, P<0.001) had significant differences between the two groups. Conclusion〓T4 tumor stage, stage IV, abdominal surgery history, tumor size > 5 cm and surgical procedures are independent factors for conversion to open surgery.
